New Kensington Thunderbolt 3 dock has 100W power delivery, dual 4K display support

Kensington has debuted a new Thunderbolt 3 dock, aimed at hot-desking and work-from-home environments, that can deliver up to 100 watts of power and drive dual 4K monitors.

The Kensington SD5600T sports a total of seven USB ports, including a single cross-compatible USB-C and Thunderbolt 3 port and six USB-A ports at 5Gbit/sec. Additionally, it has a pair of DisplayPort and HDMI ports, a 3.5mm auxiliary jack, both SD and Micro SD card slots, and a Gigabit Ethernet port. The 100W of power delivery also means that the SD5600T dock can charge even the 16-inch MacBook Pro model at maximum speed, which ships with a 96W power adapter.

When connected to a Thunderbolt 3 Intel Mac or Windows PC, it can drive up to two 4K monitors at 60Hz. It also provides data transfers speeds of up to 40Gbps for Thunderbolt 3 connection, and 10Gbps for second-generation USB-C.

The device is plug-and-play on both supported operating systems, and comes with Kensington's DockWorks software and a three-year warranty. It also supports both horizontal or vertical placement on a desktop, and is compatible with existing Kensington "zero-footprint" mounting options.

Although compatible with Thunderbolt 4 devices running either Windows or macOS, the SD5600T delivers Thunderbolt 3 specifications and performance. For Mac users, the dock requires macOS 10.14 or later.

The SD5600T dock retails for $289.99, and is available to order from Kensington's website.

My understanding, which could be incorrect, is that Thunderbolt 4 isn't faster than Thunderbolt 3 - it just adds a few additional features and security protocols to the spec. So why introduce a TB3 dock now, when TB4 is out and has only a few minor changes to implement?

This is very likely a matter of the dock not being able to meet the criteria necessary for a TB4 licence, or even just a licensing fee issue.

I’d rather have a TB4 dock myself, if I was in the market.

Docks and whatnot typically take about a year to conceptualize, design, mass produce, and ship. So, what you're seeing today, has been in the works since about November 2019.

TB4 chipsets weren't shipping in November of 2019.

I feel kind of bad for these dock manufacturers… Apple releases the 16" with a buck-wild 100 watt charger, we all complain, the dock guys come through for us… and the 16" M1 is going to require nowhere close to this much juice ¯\_(ツ)_/¯

The lack of a pass-thru TB3 port makes this dock a dead-end to me. Caldigit TS3+ is the sure-fire winner for me (it's what I have) because it has dual TB3 ports on the back. Anker just came out with a similar model that looks really nice as well.

I bought the Caldigit TS3 dock for my iMac and bolted it under my desk so I can hide all the cables/wires and also plug my second TB2 Apple monitor to it which is why it's important to have that second TB2 port to daisy chain additional TB2/TB3 devices from it. It's silly that some vendors don't include it when that's one of the advantages to Thunderbolt.
